ML5805 5.8 GHz Variable Data Rate FSK Transceiver with Integrated PA
The ML5805 is a single chip fully integrated Frequency Shift Keyed (FSK) transceiver developed for a variety of applications operating in the 5.725GHz to 5.850GHz unlicensed ISM band. The ML5805 is mode selectable for operation with digital cordless phones (DSSS or DECT) and higher data rate streaming applications like wireless audio and video.The ML5805 contains a dual-conversion low-IF receiver with all channel selectivity on chip. IF filtering IF gain and demodulation are performed on-chip eliminating the need for any external IF filters or production tuning. A post detection filter and a data slicer are integrated to complete the receiver.The ML5805 transmitter uses an adjustment-free closed loop modulator which modulates the on-chip VCO filtered data. The ML5805 includes an upconversion mixer a buffer/predriver and a power amplifier to produce a typical output power of +21dBm. A fully integrated fractional synthesizer is used in both receive and transmit modes. Power supply regulation is included in the ML5805 providing circuitisolation and consistent performance over supply voltages between 2.8V and3.6V.
